I have implemented Lisp's deftype, defvar, setq, setf, operators +,-,*,/,1+,1-,++,--,
some of my own making and am now debugging main.m. Too bad things as :
int _address;
//little endian
memcpy(&_address, (void)[s UTF8String],l);

do not work in C. This is one of the reasons why I make my own compilers sometimes.

Project arm-lisp has been posted to CMU's ftp.cs.cmu.edu/user/ai/new. Their upload directory.
